Abstract---This paper develops a new method for minimizing intersection delay based on linear and nonlinear program. On the basis of geometric construction, a new set of formulas are proposed to estimate the steady-and-oversaturation delay. As a dynamic model, it can automatically allocate the green time to obtain the minimal delay. Since the objective function of delay is linear or nonlinear, only the combination of linear and nonlinear program can be applied to random situation. The two objective functions, subject to corresponding constraints, can achieve the best split green ratios by MAT-LAB. The simulation result shows that green splits got by LP combined with NLP can obtain less delay than using fixed green splits.

Abstract—A neural network (NN)-based backstepping adaptive control is proposed for the stabilized platform system of shipborne weapons (SPOSW) with uncertain nonlinear friction torque and load disturbance. First, with the using of NN approximator, an equivalent model is developed. Where the NN is used to estimate the uncertain nonlinear friction torque. Then, based on the equivalent model, address the problem of reconstruction error and disturbance load, an adaptive backstepping control scheme is proposed for the stabilized platform system. Moreover, the analysis of stability can be completed by Lyapunov stability theory, and the convergence rate of the tracking error can be governed by the choice of the control parameter values. Finally, to demonstrate the effectiveness of the proposed control scheme, simulation results are illustrated.

Abstract—STandard for the Exchange of Product data-compliant Numerical Control (STEP-NC) is a new model of data transfer between CAD/CAM systems and CNC machines. It remedies the shortcomings of ISO 6983 by specifying machining processes rather than machine tool motion, using the object-oriented concept of Workingsteps. STEP-NC is being developed concurrently under two different subcommittees of ISO Technical Committee 184, Industrial automation systems and integration so that two different standards, ISO 14649 Data model for computerized numerical controllers and ISO 10303-238 Application interpreted model for computer numeric controllers are generated, both of which can be represented in 10303-21. In this paper, ISO 14649 NC program in Part21 relative to Example 1 in the ISO 14649-11 is explained in detail so that people can easily understand the object-oriented data model and the advantages of ISO 14649 from the actual example other than abstract and unintelligible theory. Probably, more beginners can get some revelation so that STEP or STEP-NC can get more attention and their development will be faster.

Abstract—In order to reduce the congestion of Ad Hoc network and increase the speed of routing searching , the link-disjoint paths algorithm based on ant colony optimization is proposed in this paper. The new algorithm introduces the intelligence and positive feedback of ant algorithm to link-disjoint paths algorithm to improve the probability of path optimization, sets the age domain of ant to reduce immersion, and lets the ants search routing parallelly to increase the speed. Besides, in order to reduce the occupancy of network resources, only the ants which carry the final routing data are allowed to return to the source node. The simulation results show that the new algorithm is effective and superior to the original link-disjoint paths algorithm.

Abstract—With the reformation of China’s electric power and power coal system, several difficulties emerge in planning annual coal purchase and allocation schedule, e.g., with multiple sources, multiple destinations, different shipping vessels. So it is important to research on the transportation and storage problems for regional power coal allocation planning of China. In this study, these concerns are formulated as transportation and storage problems to realize the minimization of the regional transportation and storage cost. Furthermore, an effective optimization model is proposed to solve transportation and storage problems for regional power coal allocation planning integrating storage capacities of the different kinds of enterprises in the supply chain, which considers interactive effect on multiple participants, such as regional power plants, coal transportation companies, logistics centers, coal storage centers. A case study illustrates that the model and algorithm are reasonable compared with the classic transportation model, and the sensitivity analysis improves transportation and storage strategies for regional power coal allocation planning. Results obtained in this study clearly demonstrate that this model can not only satisfy more of the actual requirements of the integral system but also offer more information to the decision makers (DMs) for reference in favor of exalting decision making quality.

Abstract—Most of the traditional dynamic multi-criteria decision-making methods utilize only differences of the systems’ evaluation values (which can be called absolute difference), then the conclusion of the evaluation is unfair to some evaluated objects. In consideration of disadvantages of the traditional method, a new method based on integration of absolute and relative differences is suggested. In this method, differences of systems’ developing status (relative difference) are taken into consideration. So more information can be put in and then produced out so as to approach reality closer. And also both the subjective and objective information are integrated. Finally, a numerical example was given to illustrate the effectiveness of the proposed method.
